FRANK H. HARTWELL, OF PITTSFIELD, NEW HAMPSHIRE.

HOSE-NOZZLE.

Specification of Letters Patent.

Patented Nov. 13,-1906.

Application filed October 31 1905. serial No. 285,288.

To all w/wm it'may concern:

Be it known that I, FRANK H. HARTWELL, a citizen of the United States, residing at Pittsfield, in the county of Merrimack and State of New Hampshire, have invented certain new and useful Improvements in Hose- Nozzles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in nozzles for hose-pipes and the object in view is to produce an apparatus whereby a thin sheet of water may be thrown from the nozzle as a shield to protect a person holding the hose in close proximity to fire and comprises various details of construction, which will be hereinafter fully described and then specifically defined in the appended claim.

My invention is illustrated in the accompanying drawings, in Which Figure 1 is a perspective view of my improved apparatus. Fig. 2 is a sectional View centrally and longitudinally through my in-' vention, and Fig. 3 is a view in side elevation of the parts disassembled.

Reference now being had to the details of the drawings by letter, A designates a nozzle adapted to fit a hose-pipe and is provided with a cylindrical body portion B, which is threaded, as at C, said portion terminating in a second portion E of less diameter, which has series of diagonallydisposed apertures leading through the wall thereof into the interior of the nozzle, which is tapering. A shoulder F is formed on the inner surface of the nozzle, through which part of said apertures open, while others open adjacent to said shoulder F. H designates a shell which has an interior surface which is threaded and adapted to fit over the threads of said portion B, and the inner circumference of the opening in said shell is greater than the outer periphery of the portion through which said perforations are formed, thus forming a chamber N, in which water is allowed to accumulate, being deflected through said apertures by the shoulder F into said chamber. A tapering shoulder B, formed near the pipecoupling end of the nozzle, is adapted to limit the movement of said shell in one direction.

K is a central ly-apertured threaded disk the threads of which are adapted to fit over the threads 0, formed in the end of the nozzle. The inner face of said disk is slightly flaring or convexed, as shown at J, and is adapted to fit tightly against the concaved 0r inclined end T of said shell, whereby the escape of any water at all between the adjacent surfaces of said disk and end of the shell may be prevented, if desired. The circumference of said threaded shell is milled, affording means whereby the shell may be turned 'to throw the same nearer to or farther away from said disk in order to regulate the amount of water which it is desired to have form a protectingsheet intermediate the person holding the hose and a fire. By turning the shell near to the disk it will be noted that a very thin sheet of water may be formed, whereas by turning the shell toward the hose the thickness of the sheet of water may be increased, thereby affording a simple and efficient means whereby the volume of water which is fed in a disk-like sheet may be regulated to adapt the apparatus for variousintensities of heat.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is-

In combinationwith a nozzle adapted to have threaded connection with the end of a pipe, a shell having a corrugated circumference and threads upon its inner surface adapted to engage threads upon the circumference of said nozzle, a portion of the inner surface of the shell being threadless intermediate the threaded portion and the end of said shell,-

the circumference of the nozzle having a tapered shoulder adapted to limit the movement of said shell in one direction, one end of the nozzle being contracted and provided with screw-threads, a smooth threadless portion intermediate the two threaded parts of the nozzle, the inner surface of the nozzle having a shoulder and the wall of the nozzle having apertures leading throu h said shoulder upon the inner surface of the nozzle and also apertures leading through the portion intermediate the threads engaged by said In testimony whereof lhe'reunto afliX my shellland the thrhrzeradliescs1 circliiimference of the I signature in the presence of two Witnesses. nozz e, and a t ea e is mounted upon the end of the nozzle and having an inclined l FRANK HARTWELL' surface of the inner face thereof conforming Witnesses:

said shell, as shown and described. NATT A. CRAM.
